Did anyone say it was an optical shrink? I assumed a fresh redesign because of the copper.

<how can they go from 184 mm2 to 104 mm2 with an optical shrink for
the K7 if they stay with 6 metal?>
Why do you have a concern here?
For fully scaled linear shrink of 41% the area
must be 184/2=92mm2. However, the C4 bumps
do not scale at the same rate, therefore
there must be some increase from the 92mm,
with some re-layout of the top layer.
Am I missing something here?

Kapkan - <I don't see how can they go from 184 mm2 to 104 mm2 with an optical shrink for the K7 if they stay with 6 metal?>

Easy. It's not an optical shrink if the die size shrinks. For an optical shrink from a previous generation, the die size remains the same, with a bunch of dead area around the periphery of the die. It's got to be a bona fide design shrink. They could still stay with 6 layer metal, especially since they are going to Cu. Could be seven, but my guess is six, and I stress this is a guess.
